Functional characterization of plant specific Indeterminate Domain (IDD) transcription factors in tomato (Solanum lycopersicum L.).

Plant-specific transcription factors (TFs) are responsible for regulating the genes involved in the development of plant-specific organs and response systems for adaptation to terrestrial environments. This includes the development of efficient water transport systems, efficient reproductive organs, and the ability to withstand the effects of terrestrial factors, such as UV radiation, temperature fluctuations, and soil-related stress factors, and evolutionary advantages over land predators. In rice and Arabidopsis, INDETERMINATE DOMAIN (IDD) TFs are plant-specific TFs with crucial functions, such as development, reproduction, and stress response.

Engineering homoeologs provide a fine scale for quantitative traits in polyploid.

Numerous staple crops exhibit polyploidy and are difficult to genetically modify. However, recent advances in genome sequencing and editing have enabled polyploid genome engineering. The hexaploid black nightshade species Solanum nigrum has immense potential as a beneficial food supplement.

Mediates NH-Dependent Root Hair Growth Suppression and Expression in Rice ( L.).

Root hairs play crucial roles in the roots, including nutrient uptake, water assimilation, and anchorage with soil, along with supporting rhizospheric microorganisms. In rice, ammonia uptake is mediated by a specialized ammonium transporter (AMT). AMT1;1, AMT1;2, and AMT1;3 have been extensively studied in relation to nitrogen signaling.

Newly Discovered Alleles of the Tomato Antiflorigen Gene Provide a Range of Plant Compactness and Yield.

In tomato cultivation, a rare natural mutation in the flowering repressor antiflorigen gene () induces precocious shoot termination and is the foundation in determinate tomato breeding for open field production. Heterozygous () mutants in the florigen gene in the background of provide a heterosis-like effect by delaying shoot termination, suggesting the subtle suppression of determinacy by genetic modification of the florigen-antiflorigen balance could improve yield. Here, we isolated three new alleles from the tomato germplasm that show modified determinate growth compared to including one allele that mimics the effect of heterozygosity.

Narrow Metaxylems Enhance Drought Tolerance and Optimize Water Use for Grain Filling in Dwarf Rice.

Rice cultivation needs extensive amounts of water. Moreover, increased frequency of droughts and water scarcity has become a global concern for rice cultivation. Hence, optimization of water use is crucial for sustainable agriculture.

Type III Effector RipJ Triggers Bacterial Wilt Resistance in .

causes bacterial wilt disease in solanaceous crops. Identification of avirulence type III-secreted effectors recognized by specific disease resistance proteins in host plant species is an important step toward developing durable resistance in crops. In the present study, we show that effector RipJ functions as an avirulence determinant in LA2093.
