Abstract
The ribosomal protein contains complex structures that belong to polypeptide glycoprotein family, which are involved in plant growth and responses to various stresses. In this study, we found that capsicum annuum 40S ribosomal protein SA-like (CaSLP) was extensively accumulated in the cell nucleus and cell membrane, and the expression level of CaSLP was up-regulated by Salicylic acid (SA) and drought treatment. Significantly fewer peppers plants could withstand drought stress after CaSLP gene knockout. The transient expression of CaSLP leads to drought tolerance in pepper, and Arabidopsis's ability to withstand drought stress was greatly improved by overexpressing the CaSLP gene. Exogenous application of SA during spraying season enhanced drought tolerance. CaSLP-knockdown pepper plants demonstrated a decreased resistance of Pseudomonas syringae PV.tomato (Pst) DC3000 (Pst.DC3000), whereas ectopic expression of CaSLP increased the Pst.DC3000 stress resistance in Arabidopsis. Yeast two-hybrid (Y2H) and bimolecular fluorescence complementation (BiFC) results showed that CaNAC035 physically interacts with CaSLP in the cell nucleus. CaNAC035 was identified as an upstream partner of the CaPR1 promoter and activated transcription. Collectively the findings demonstrated that CaSLP plays an essential role in the regulation of drought and Pst.DC3000 stress resistance.

Aims
Molecular Horticulture aims to publish research and review articles that significantly advance our knowledge in understanding how the horticultural crops or their parts operate mechanistically. Articles should have profound impacts not only in terms of high citation number or the like, but more importantly on the direction of the horticultural research field.
Scope
Molecular Horticulture publishes original Research Articles, Letters, and Reviews on novel discoveries on the following, but not limited to, aspects of horticultural plants (including medicinal plants):
▪ Developmental and evolutionary biology
▪ Physiology, biochemistry and cell biology
▪ Plant-microbe and plant-environment interactions
▪ Genetics and epigenetics
▪ Molecular breeding and biotechnology
▪ Secondary metabolism and synthetic biology
▪ Multi-omics dealing with data sets of genome, transcriptome, proteome, metabolome, epigenome and/or microbiome.
The journal also welcomes research articles using model plants that reveal mechanisms and/or principles readily applicable to horticultural plants, translational research articles involving application of basic knowledge (including those of model plants) to the horticultural crops, novel Methods and Resources of broad interest.
In addition, the journal publishes Editorial, News and View, and Commentary and Perspective on current, significant events and topics in global horticultural fields with international interests.
