Nigeria has a wide range of arable rice growing environments including the inland valleys. Despite being the largest rice producer in West Africa, Nigeria is still a rice deficit nation. One of the major constraints to rice production in the inland valleys of Nigeria is iron (Fe) toxicity. The understanding of the genetic basis of Fe tolerance mechanisms can provide useful information for the breeding of tolerant varieties. Based on the aforementioned, the research was conducted to study the general and specific combining ability for yield and its components and to estimate the gene action for seed yield and its components. Eight rice varieties were planted and crossed using incomplete diallel mating design to generate 28 hybrids which were evaluated along with the eight parents and two checks (Alhaji Baba and Ewodufagi) at Edozhigi during the 2017/2018 dry season. Data were collected on grain yield, days to 50% flowering, number of tillers, number of leaves, plant height, panicle length, number of seeds per panicle, panicle exertion, number of effective tillers, 1000 grain weight, first and second iron toxicity scores were subjected to diallel analysis of variance (ANOVA) for both parents and hybrids, using Statistical Analysis System (SAS) software package (2002). The results from the study are summarized as follows GCA and SCA mean squares were significant for most measured traits under iron toxicity hotspot, indicating importance of additive and non-additive gene action for controlling the traits. There was preponderance of additive gene effects over non-additive gene effects for all the traits measured indicating that additive gene action was more important in the inheritance of the traits under iron toxicity hotspot. FARO 52, SUAKOKO 8, CK-21 and CK-43 were good general combiners for grain yield under iron toxicity hot spot conditions.

Sapria, a holoparasitic plant of Rafflesiaceae is still understudied in term of anatomical, even more in histoanatomical study. This study aimed to perform preliminary observation on Sapria himalayana Griff. f. albovinosa morphology on its early and late stage of flower bud development inside its host, Tetrastigma laoticum Gagnep. (Vitaceae). The results show the progression from the early flower bud as it starts to grow in the host vascular cambium area towards proximal direction to reach the host xylem and distal direction to reach the host phloem and to reach the next stage of the life cycle, into the late flower bud where differentiation occurs. In late flower bud, some primordial of the organs are visible as the flower bud grows larger distally towards the periderm. This development pattern is similar to the progression of development in the previous studies in Rafflesia and Rhizanthes, where endophytic growth was observable in both proximal (xylem area) and distal (peridermal). Future comparative study is encouraged, especially to compare between Sapria species and between different stages of growth. Although, an efficient method and less invasive way of sampling is encouraged to prevent decline of Sapria species in the wild.

During plant-microbe interactions, plant immune signaling relies significantly on post-translational modifications (PTMs) to induce rapid downstream changes. Organization at protein level is extensively complex and various forms of PTMs of transcript products provide a unique system in maintaining such an organization. With current proteomic research some detailed mechanisms of these PTMs have started to be uncovered. Pathogens also take PTMs as a virulence strategy to overturn host immunity through the activities of their effector proteins. In this review, we will address the importance of PTMs other than phosphorylation in plant defense response.

Coke production is one of the important sources of pollution from steel industries. The effects of coke (sludge of iron and steel) on seed germination and growth of Vigna radiata (L.) R. Wilczek, Vigna mungo (L.) Hepper and Vigna unguiculata (L.) Walp. were recorded. The seed germination percentage of V. radiata was increased with increase in coke concentration treatment at 25-50% as compared to control treatment in petri dish. Seedling length and root growth performance of V. radiata was also slightly increased with the increase in coke concentration treatment at 75 and 100% as compared to control. The seed germination percentage and root length of V. mungo was reduced with increase in coke concentration treatment at 25%. The obtained results showed more positive effects of coke on seed germination and seedling growth performance of V. unguiculata than V. mungo and V. radiata. Meanwhile, experiment showed decrease in seedling vigor index of V. radiata and V. mungo with the increase in concentration of coke at 100% as compared to control. A gradual increase in seedling vigor index for V. unguiculata with the increase in coke concentration was observed. The coke extracts treatment influence on the seedling tolerance indices of V. radiata, V. mungo and V. unguiculata. The better tolerance to coke treatment in all bean crops might be mainly due to some resistance potential ability of seedlings to coke concentration.

A previous study showed that excessive GAs/DELLAs altered the arrangement, shape and frequency of hairs in root tips of A. thaliana seedlings by acting from the root sub-epidermal tissues. The present study showed that excessive GAs/DELLAs also modified root tip cell size/number in A. thaliana seedlings. While excessive DELLAs shortened and widened the root epidermal, cortical, endodermal and pericycle cells, excessive GAs, excepting the epidermal cells, generally narrowed them. However, no root cell size changes occurred when gai-1 was over-expressed at the root epidermis. Also, excessive DELLAs induced extra cells at the root epidermis, cortex, endodermis and pericycle and lateral root outgrowth, whereas excessive GAs induced extra cells at the root cortex and pericycle. Thus, excessive GAs/DELLAs might modify root tip cell size/number by acting from the sub-epidermal tissues of the root. This, in turn, might impact on the root hair patterning & abundance and the root architecture.

Millions of hectares devoted to cereal production in Africa were affected by Striga infestation across locations and time. A study was conducted in 2012 and 2013 rainy seasons at the Teaching and Research Farms of Niger State College of Agriculture, Mokwa and the Teaching and Research Farms of Federal University of Technology, Minna, in the Southern Guinea Savanna ecology of Nigeria to determine cereal / legume intercropping and N fertilization effects on Striga infestation, Soil C and N and grain yield of maize. The treatments consisted of four inorganic N fertilizer levels (0, 60, 90, 120 kg ha), alternate hill and same hill intercropping of Aeschynomene histrix. Intercropping maize with A. histrix has the potential of reducing Striga parasitism with about 33-47% with respect to Striga shoots per m and Striga shoots per plot thus, enhancing maize grain yield. The use of herbaceous legumes in intercropping contributed about 58% SOC and 52-57% reduction in number of S. hermonthica due to application of N using urea, thereby helping to control Striga infestation. Intercropping maize with A. histrix improved the soil organic matter and hence, the physical, chemical and biological properties of the soil for good crop growth. Incorporation of the A. histrix residues substantially increased the soil N content. There was response to inorganic N fertilizer application, suggesting the need for N application to maize for optimum grain yield. Nitrogen rate of 60 kg ha was optimum for maize yield in the study area.

Zamia inermis is a dioecious cycad endemic to the State of Veracruz that is on the risk extinction. Sexspecific markers are important in understanding the mechanism of sex determination. However, since little is known about the mechanism of sex determination in Z. inermis, we proposed looking for Inter-simple Sequence Repeats (ISSR) markers that could be linked to sexual expression in this species. Using DNA bulk samples of male and female genotypes and 6 ISSR primers, a female marker (~867 bp) was identified with primer ISSR-18, which was present in 66% of the DNA mixtures of the female genotypes analyzed. The results of the Principal Coordinate Analysis performed revealed a tendency for clustering of genotypes of the same sex.

Assessment of transplanting effects at different ages of seedling development on morphological and yield attributes in two landraces (SOMBO/MKW/2017 and NDAGBACHI/MKW/2017) of Nigerian pepper (Capsicum spp.) was studied during the planting season of 2017. The Capsicum landraces were obtained from local farmers in Mokwa, Niger State. The study was conducted at the experimental garden, Federal University of Technology, Minna, Niger State. Transplants were made at different ages (3, 4, 5 and 6 weeks after planting). The experimental design used was a Complete Randomized Design (CRD) with four replications of each treatment. Quantitative data obtained were pooled for analysis. Analysis of Variance (ANOVA) was used to compare the various mean values. Duncan Multiple Range Test (DMRT) post hoc test was used to separate the means. All values were considered significant at p<0.05. The result showed some interesting variations among the different ages of transplants; the results of the plant height at maturity and number of leaves for NDAGBACHI/MKW/2017 revealed that week 3 had the highest plant height (33.00 cm) at maturity and also the highest number (39.50) of leaves. However, these values were not significantly different (p>0.05) from all other weeks. The results for plant height at harvest and number of branches revealed that week 4 recorded the highest height (37.75cm) at harvest and highest number (8.00) of branches, but is not statistically different (p>0.05) from other weeks. For SOMBO/MKW/2017, Week 4 recorded highest in terms of plant height (30.08cm) at maturity, plant height (32.50cm) at harvest and number of branches (9.25). These values were significantly different (p<0.05) from other weeks. For NDAGBACHI/MKW/2017, Week 3 produced the highest number of fruits/plant (28.00) but bears no significant difference (p>0.05) to all other weeks. However, for SOMBO/MKW/2017, Week 4 recorded the highest number of fruits/plant (35.00) and is significantly different (p<0.05) from week 3 and 6 but statistically the same with week 5. In both landraces, Week 3 produced the highest number of seeds/fruit, but is statistically the same (p>0.05) with other weeks. It is therefore concluded that variation in transplanting age tend to influence certain morphological and yield attributes in Nigerian pepper landraces. Also, 3 and 4 week old transplants seem to be the best age to produce more yields for NDAGBACHI/MKW/2017 and SOMBO/MKW/2017 respectively. Further research works should be done to test for other higher ages at transplanting and also for different landraces in order to arrive at a sound conclusion.

The Capsicum landraces were obtained from local farmers in Mokwa, Niger State. The study was conducted at the experimental garden, Federal University of Technology, Minna, Niger State. Transplants were made at different ages (3, 4, 5 and 6 weeks after planting). The experimental design used was a Complete Randomized Design (CRD) with four replications of each treatment. Quantitative data obtained were pooled for analysis. Analysis of Variance (ANOVA) was used to compare the various mean values. Duncan Multiple Range Test (DMRT) post hoc test was used to separate the means. All values were considered significant at p<0.05. The result showed some interesting variations among the different ages of transplants; the results of the plant height at maturity and number of leaves for NDAGBACHI/MKW/2017 revealed that week 3 had the highest plant height (33.00 cm) at maturity and also the highest number (39.50) of leaves. However, these values were not significantly different (p>0.05) from all other weeks. The results for plant height at harvest and number of branches revealed that week 4 recorded the highest height (37.75cm) at harvest and highest number (8.00) of branches, but is not statistically different (p>0.05) from other weeks. For SOMBO/MKW/2017, Week 4 recorded highest in terms of plant height (30.08cm) at maturity, plant height (32.50cm) at harvest and number of branches (9.25). These values were significantly different (p<0.05) from other weeks.

The flower bud of Rafflesia patma Blume following the protocorm stage of the flower will undergo rapid cell growth followed by the differentiation stage which lead to the later stage of the flower bud morphogenesis into the floral organs. During this transitional period of the flower bud, we revisited our R. patma flower bud microscope slide samples and some images from the previous study in [MURSIDAWATI & SUNARYO, 2012] to examine how the R. patma tissue behave prior to the late differentiation stage. We discovered that there are several types of meristematic cells in the R. patma early flower bud tissue: The elongated cells in the basal/proximal region of the bud where it in proximity with host xylem, then a column of non-elongated cells where ovary will develop in the later stage (in female flower), and in the apical/distal region of the flower bud, we found a densely packed meristematic cells where in the later flower bud this area will be developed into the protective bracts, perigone lobes, and central disc as later seen in the late flower bud tissue. During the late stage of the flower bud growth, the flower bud also inhibits growth of 1-2 vascular bundles, altering few others host vascular bundles surrounding the flower bud, while on the other side the root vascular bundle growth is just normal. This growth mechanism can minimize the host vasculature damage if multiple buds are growing the same growth direction.
