The GRAS transcription factor family is a plant-specific regulatory proteins that play fundamental roles in various biological processes. The acronym “GRAS” stands for “Gibberellic Acid Insensitive, Repressor of GA1-3 and Scarecrow,” representing three of its founding members. Additionally, GRAS members are instrumental in orchestrating symbiotic interactions, stress responses and other vital physiological functions. The N-terminal of GRAS protein is very diverse, but the C-terminal GRAS domain is conserved. The GRAS proteins’ C-terminal conserved domain directly influences how they work. For instance, in the Arabidopsis plant, alterations to the phenotype of the slender rice 1 (SLR1) and Repressor of GA (RGA) proteins result from mutations in this domain. More than 30 plant species have been found to have GRAS proteins, which have been classified into 17 subfamilies so far. This review focused on the structural characteristics of GRAS proteins, their growth and diversity in plants, GRAS-interacting protein complexes and their function in biological processes. Moreover, GRAS proteins also mediate responses to phytohormones, such as gibberellins and strigolactones and regulate phytochrome signaling, which is crucial for light perception and plant growth. It also discussed the significance of GRAS proteins throughout various biological processes in plants. Additionally, we outlined recent studies that used CRISPR-Cas9 technology to modify GRAS genes in a plant for various features. Additionally, there have been discussions of using GRAS genes in agricultural enhancement efforts.
GRAS转录因子家族是植物特异性调控蛋白，在多种生物过程中发挥重要作用。首字母缩略词“GRAS”代表“Gibberellic Acid Insensitive, Repressor of GA1-3 and稻草人”，代表了它的三个创始成员。此外，GRAS成员在协调共生相互作用、应激反应和其他重要生理功能方面发挥重要作用。GRAS蛋白的n端结构非常多样化，但c端结构域是保守的。GRAS蛋白的c端保守结构域直接影响它们的工作方式。例如，在拟南芥植物中，细长水稻1 (SLR1)和GA抑制因子(RGA)蛋白的表型改变是由该结构域的突变引起的。目前已发现有30多种植物含有GRAS蛋白，并将其划分为17个亚科。本文综述了GRAS蛋白的结构特征、在植物中的生长和多样性、GRAS相互作用蛋白复合物及其在生物过程中的功能。此外，GRAS蛋白还介导对赤霉素和独角酯内酯等植物激素的反应，并调节光敏色素信号，这对光感知和植物生长至关重要。并讨论了GRAS蛋白在植物各种生物过程中的意义。此外，我们概述了最近使用CRISPR-Cas9技术修改植物中各种特征的GRAS基因的研究。此外，也有关于在农业改良工作中使用GRAS基因的讨论。

Background: Tobacco mosaic virus (TMV) stands as a highly studied virus and consequently, its features and composition are extensively understood. It has been found to induce diverse infections in numerous plant species, with tobacco leaves being notably affected, showing mottled browning. Presently, the sole available method to control its spread is by removing infected plants. Understanding codon use bias is crucial as it could play a pivotal role in molecular interventions aimed at halting the virus’s replication and multiplication, thereby helping to contain its propagation. Methods: Currently, the research focuses on assessing codon bias within six genes related to the replicase/coat protein of TMV, namely TMVgp1, TMVgp2, TMVgp3, TMVgp4, TMVgp5 and TMVgp6. To conduct this analysis, various methods such as relative dinucleotide abundance, relative synonymous codon usage (RSCU), neutrality plot and parity rule 2 (PR2) plot were employed. Result: All of the identified genes had a modest codon bias, according to the study on codon usage, as well as the function of mutation pressure in gene TMVgp3 and natural selection in genes TMVgp1, TMVgp2, TMVgp4, TMVgp5 and TMVgp6. The Research into codon use bias showed that the TMV virus’s chosen genes are subjected to naturally occurring selection as well as mutational pressure.

Background: Cotton crop is sensitive in its young stages i.e. stand establishment. Cotton seeds are fuzzy and messy in handling and field sowing. Delinting is a necessary process done commonly using acids and are comprehensively not protective. Optimal plant population, growth and persistence are strongly influenced by germination and establishment. In line with this, it is necessary and needful of an hour to find an alternative, eco-friendly, ecologically safe and low cost seed treatment method. Methods: The experiment was conducted in two methods viz., a petridish method and roll-towel method with seed treatment methods viz., cowdung and red earth mix treated with and without biofertilizer and compared with acid-delinted and fuzzy seeds. The germino-metrics were determined using GerminaR package, an interactive web application and statistical analysis was performed using R software package v. 4.2.1. Result: The summative effect of seed treatment with fresh cow dung, red earth and biofertilizer (Azospirillum and Phosphobacteria) per kg of seeds at respective quantities (0.5:0.25:0.12) recorded significantly maximal germination indices and seedling growth determinants. This present study would be a complementary to comprehensively promote the use of indigenously available natural materials as an alternative to acids in cotton seed delinting.

Background: Inclusion of high value vegetable crops like onion and potato in soybean based crop sequence may help to improve the productivity and profitability on sustainable basis. Nutrient management and cropping sequence are two important factors which affect productivity and profitability of crop. As such, information on soybean followed by onion and potato is lacking and it will be very useful for exploring the productivity and profitability of soybean followed by high value vegetable crop sequence. Methods: The data pertaining to growth characteristics, yield characteristics, gross monetary returns and net monetary returns of Soybean ( kharif ) and Onion or Potato (rabi ) was collected at regular interval in 2017-18, 2018-19 at Agronomy Farm, Dr. PDKV, Akola which was analyzed statistically in RBD (Randomized Block Design) and SPD (Split Plot Design). Result: S1- soybean-onion recorded more production efficiency than S2- soybean-potato. S1- soybean-onion reported greater economic efficiency than S2- soybean-potato. Soybean crop supplied with IN3 (100% RDN applied with FYM@ 5 t per ha and biofertilizer) registered highest production efficiency and economic efficiency than IN1 ( 50% RDN applied with FYM5 t per ha and biofertilizer) to soybean and found at par with IN2 (75% RDN applied with FYM5 t per ha and biofertilizer) to soybean. Rabi crop (onion/potato) supplied with F3 (125% RDF) level registered significantly greater production and economic efficiency than lower levels of recommended dose nutrient.

Background: Vascular streak dieback (VSD) is an important disease in cocoa and a decrease in nutrient supply is indicated to increase the severity of this disease. This study aimed to analyze the direct and indirect effects of nutrients that play a role in protecting cocoa plants from VSD. Methods: The research location was selected based on criteria such as being a smallholder cocoa plantation area, having 5-10-year-old plants and the presence of VSD disease. A sampling technique for observing disease severity was systematically conducted, with the main sample being farmers’ plantations. Cocoa leaf samples were taken from branches at one-third of the plant height, specifically from the upper canopy (leaves 3-4), which were physiologically mature, healthy and dark green. The variables observed were disease severity and cocoa leaf nutrient contents. The influence of N, P, K, Mg, Ca, Fe, Mn, B, Cu and Zn on VSD severity was analyzed using path analysis. Result: The results showed that disease severity was related to nutrient content in the leaves. The cocoa leaf nutrients that have a direct influence on the increase in VSD disease severity are K, Ca, Mn and Cu, while nutrients N, P, Mg, Fe, B and Zn have a direct influence on reducing VSD disease severity. Nutrients N and P have a significant direct influence, whereas nutrient K has a significant indirect influence through its interaction with nutrients N and P in reducing VSD disease severity.

Background: Tomato (Lycopersicon esculentum Mill) is a widely cultivated vegetable crop worldwide, including in Fiji. However, the suitability of tomato cultivation under greenhouse conditions in the central region of Fiji, which experiences salinity issues, remains unclear. Methods: A pot experiment was conducted at the Instructional Agricultural Farm Complex of the College of Agriculture, Fisheries and Forestry, Fiji National University, Fiji, to determine the effect of different levels of salinity on the growth and yield of tomato (Lycopersicon esculentum Mill) varieties. The experiment included two factors: three tomato varieties (V1= Melrose; V2= Alton; V3= Alafua Large) and four levels of NaCl salinity (T1= Control; T2= 2 dSm-1; T3= 4 dSm-1 and T4= 8 dSm-1) randomized thrice in a randomized complete block design. The effects of various varieties and salinity levels on tomato yield were studied in this experiment. Result: The results revealed that variety Alafua Large performed comparatively better in all cases. This recorded maximum fruit length (4.22 cm), fruit breadth (3.31 cm), individual fruit weight (45.60 g), number of fruits (7.83) and fruit yield (352.10 g) whereas Alton recorded the minimum of the above yield attributes. In the case of the combined effect of variety and salinity, Alafua Large showed better yield (432.17 g and 394.51 g) per plant than the other varieties when combined with the lower salinity level i.e., EC 2 dSm-1 and 4 dSm-1, respectively. The yield of tomato varieties declined with the increasing salinity level condition. The yield of Alafua Large was 194.54 g when applied with the highest level of salinity i.e., EC 8 dSm-1 and the yield of Alton was 64.69 g which was the lowest yield among the varieties with the highest level of salinity condition. Therefore, from the results, Alafua Large is comparatively more salt tolerant than the other varieties which were studied in this experiment.

Background: Selection of a suitable planting time is one of the key factors for obtaining a desirable rice grain yield. This study focuses on the effect of planting date on the key agronomic traits and provides useful information of an optimal planting window to maximize grain yield of Bangabandhu dhan100 in the cold-prone Rangpur region, Bangladesh Methods: The study was conducted at the Rangpur regional station farm of the Bangladesh Rice Research Institute from October 2021 to June 2022. The selected cultivar was seeded on eight different dates at a 15-day interval, starting on October 16. Time series data on agronomic parameters including seedling biomass, leaf number of seedlings, and tiller number per plant were collected at a 15-day interval. Result: A good relationship was found between accumulated GDD (growing degree days) and the associated leaf number per plant, and the highest leaf number was observed with the early seeding. Similarly, seedling biomass yield depended on accumulated GDD, and it was found to be higher at early seeding than late seeding. The tillering pattern of Bangabandhu dhan100 was influenced by planting date and reached its peak at 60 days after planting for all seeding dates. The highest tiller number (368/plants) was found when the cultivar was planted on December 1. Total biomass showed an increasing trend after planting and reached its maximum of 13.9 t/ha with December 1 planting. Planting time significantly influenced the grain yields, and the highest yields were observed during plantings between 1 and 16 December; yields gradually decreased with the advancement of planting dates. This finding provided a good idea for the selection of an optimal planting time for Bangabandhu dhan100 to maximize grain in the Rangpur region, Bangladesh.
