Article Synopsis
- Resource-poor areas facing moisture deficits suffer from iron deficiency in rice cultivation, leading to a study that evaluated the Bengal and Assam Aus rice varieties for growth traits in an iron-deprived environment.
- A new scoring scale classified rice tolerance to iron deficiency from 0 (most tolerant) to 9 (most susceptible), revealing four key candidate genes responsible for various growth traits such as shoot length and root characteristics.
- The study identified BR16 as a superior donor with enhanced growth metrics compared to RA23, while also exploring how genetic variations in the candidate genes contribute to abiotic stress tolerance in rice.
Article Synopsis
- The study investigates the role of lipid droplets (LDs) and their associated proteins in seed germination and lipid metabolism, focusing on how natural selection impacts these processes in oilseeds.
- Analysis of LD-associated genes from key oil crops revealed that positive selection significantly influences the evolution of these genes, particularly in oleosins and TAG-lipases, while some genes showed neutral or purifying selection.
- The findings highlight variations in selection pressures across different plant species, with many genes related to lipid organization under strong selection, underscoring the complex interplay between mutation, gene expression, and evolutionary adaptation in oil-rich seeds.
Evolutionary dynamics of AP2/ERF and WRKY genes, the major components of defense response were studied extensively in the sesame pan-genome. Massive variation was observed for gene copy numbers, genome location, domain structure, exon-intron structure and protein parameters. In the pan-genome, 63% of AP2/ERF members were devoid of introns whereas >99% of WRKY genes contained multiple introns.

Potato () is regarded as a future food crop by FAO to ensure food security, which is severely affected by salinity. The growth of the potato plant is inhibited under salt stress due to osmotic stress-induced ion toxicity.

Sequence analysis indicated that it shared maximum identity to ToLCNDV isolates from pumpkin and ashgourd. Infectious clones of isolate KAN-6 along with two other ToLCNDV isolates (MOD-21 & FAI-19) obtained from potato fields of Modipuram and Faizabad, India were produced and used in symptom expression studies in and potato plants through agro-inoculation.

Mitochondrial DNA B Resour
February 2017
Complete mitochondrial genome of , A mating type (MT) with a size of ≅37,767 bp was sequenced. A total of 53 protein-coding genes are predicted on both strands, including 25 , 2 , and 18 respiratory proteins. Gene order of AMT was consistent with that established in A, despite high level of polymorphism in both coding and non-coding regions.
