Investigating how reproductive traits in rice respond to abiotic stress.

Oryza sativa is one of the most important crops and a food source for billions of people. Anthropic global warming, soil erosion, and unstable environmental conditions affect both its vegetative and reproductive growth, and consequently the final yield of its cultivation. The reproductive phase starts with the transition of apical meristem from vegetative to reproductive, which develops into a panicle, proceeds through the differentiation of the floret, and, after fertilization, the filling of the grain.

The response of oilseed rape to sulfur (S) restriction usually consists of increasing the components of S utilization efficiency (absorption, assimilation and remobilization) to provide S to seeds. However, source-sink relationships and S management in developing seeds under sulfate restriction are poorly understood. To address this, impacts of sulfate restrictions applied at "visible bud" or "start of pod filling" stages were studied with two genotypes (Aviso, Capitol) showing similar seed yield but higher seed weight and lower number of seeds per plant for Capitol under non-limited conditions.

During vegetative growth, plants undergo various morphological and physiological changes in the transition from the juvenile phase to the adult phase. In terms of stress resistance, it has been suggested that plants gain or reinforce disease resistance during the process of maturation, which is recognized as adult plant resistance or age-related resistance. While much knowledge has been obtained about changes in disease resistance as growth stages progress, knowledge about changes in plant responses to pathogens with progressing age in plants is limited.

Central Asia, located at the heart of Eurasia, is renowned for its varied climate and vertical vegetative distribution, which support diverse biomes and position it as a global biodiversity hotspot. Despite this ecological richness, Central Asia's fungal diversity, particularly wood-inhabiting macrofungi, remains largely unexplored. This study investigates the diversity, ecological roles, and potential distribution of poroid Hymenochaetoid fungi in the region.
