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.","PeriodicalId":13398,"journal":{"name":"Indian Journal Of Agricultural Research","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135739253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":13398,"journal":{"name":"Indian Journal Of Agricultural Research","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135739263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":13398,"journal":{"name":"Indian Journal Of Agricultural Research","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136341266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":13398,"journal":{"name":"Indian Journal Of Agricultural Research","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136341579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
