Abstract ：
INDETERMINATE DOMAIN containing proteins (IDD) are plant-specific transcriptional factors with a diverse range of roles in plants. Among the 15 IDD genes in rice, a staple food crop for the world, only about half have been functionally characterized. To elucidate the function of the remaining members, we created loss-of-function mutants using the CRISPR genome editing technique. Although no mutant exhibited obvious growth phenotypes, the Osidd6 mutant was completely sterile. By genetic crossing, we showed that both the male and female gametophytes were defective in the mutant. Histochemical staining and thin sectioning revealed that microspore development was compromised, likely due to a delay in tapetum degeneration. We also showed that meiosis was impaired in the mutant, resulting in defective megaspore development. Through a series of experiments, including transcriptome analysis, reverse transcription-quantitative polymerase chain reaction (RT-qPCR), in situ hybridization, beta-glucuronidase (GUS) staining with promoter-GUS transgenic plants, yeast one-hybrid method, a dual-visible reporter assay, and transcriptional activity assay, we demonstrated that OsIDD6 is expressed in all cell types in the male and female reproductive organs and that the OsIDD6 protein directly regulates genes potentially having a role in meiosis and tapetum development. Since reproductive development is directly related to crop yield, OsIDD6 could be an important target for genetic manipulation in rice breeding.

Abstract ：
Prolonged exposure to low temperatures during agricultural production often leads to fruit malformation in crops, significantly reducing market value. However, the underlying molecular mechanisms remain poorly understood. In this study, we identify sugar transport protein 2 (STP2) as a critical regulator of tomato fruit locule development under cold conditions. Low temperatures impair long-distance sucrose transport from leaves to shoot apices, resulting in reduced accumulation of glucose and arabinose. In response, STP2 expression is strongly upregulated in shoot apices, promoting glucose and arabinose transport. We found that the CLAVAT3-WUSCHEL (CLV3-WUS) regulatory module, which governs locule formation, relies on STP2-mediated sugar transport for CLV3 arabinosylation. Overexpression of STP2 promotes glucose and arabinose accumulation in shoot apices, enhances CLV3 arabinosylation and the WUS suppression, mitigating the multi-locular malformations induced by low temperatures. Conversely, disruption of STP2 function exacerbates locule number increases under low temperatures, which could not be rescued by exogenous sugar supplementation. Our findings reveal a key mechanism by which STP2-mediated sugar transport supports CLV3 arabinosylation to maintain fruit locule development under low temperatures, offering potential strategies to alleviate fruit malformations in winter crop cultivation.

Abstract ：
How do self-pollinating plants maximize fertility under pollen-limiting stresses? A recent study shows that some Brassicaceae species employ a dynamic two-step self-pollination mechanism. Flower closure after initial opening enables a second pollen deposition, doubling the pollen load and rescuing seed set under heat stress or fertilization failure.

Abstract ：
Plants are essential for life as we know it on Earth. They oxygenate the atmosphere, regulate the climate, and comprise much of the primary producers underpinning complex food systems. In the 1980s, a multinational group of plant scientists chose the small angiosperm-Arabidopsis thaliana-to serve as the model flowering plant for genetic and molecular studies that would be leveraged to produce vast new datasets, resources, and tools. The rationale they used to persuade funding agencies to make significant investments and focus intense effort on this single plant species was to produce a deep fundamental knowledge of the biology of plants and to apply this knowledge to valuable, but typically less tractable, plant species. Over the past 40 yr, Arabidopsis has emerged as the most powerful and versatile plant model to uncover core biological principles and served as a prototyping system to test advanced molecular and genetic concepts. We argue that the emerging challenges of accelerating climate instability and a rapidly growing global population call for renewed and robust investments in fundamental plant biology research. Leveraging the power of Arabidopsis research, resources, datasets, and global collaborative community is more important than ever. This commentary lays out a vigorous defense of foundational, i.e. "basic," plant science research; describes that often, Arabidopsis is preferable to working directly in crops; highlights several transformative applications generated from basic plant research; and makes the argument that plant science is vital to the survival of humanity.

Abstract ：
Trichomes of aerial plant organs contribute to adaptive responses to abiotic and biotic stresses. In horticultural plants, increasing glandular trichome density is an effective breeding strategy to enhance resistance to herbivores through promoting the capacity to produce specialized metabolites. The regulatory mechanisms controlling multicellular trichome formation are only partially understood. In this study, we reveal that SlGRAS9 and SlMYC1 transcription factors form a regulatory module controlling glandular trichome formation in multiple tissues. Knockout of SlGRAS9 or overexpression of SlMYC1 in tomato leads to an increased number of type VI glandular trichomes and to higher terpenoid accumulation in leaves, petals, sepals, and fruits. Conversely, knockout of SlMYC1 results in reduced type VI glandular trichomes number and terpenoid levels. Promoter-binding and genetic interaction experiments revealed that SlGRAS9 negatively regulates the transcription of SlMYC1, indicating that the regulation of glandular trichome formation by SlGRAS9 is dependent, at least partly, on SlMYC1. Consistently, both SlGRAS9 knockout and SlMYC1 overexpression result in higher tolerance of tomato plants to spider mites and aphids. In addition to adding some of the missing components to the mechanisms controlling formation of type VI glandular trichome, our findings also uncover new targets for breeding strategies aimed at improving crop protection against pest invasion, thus ensuring crop yield resilience to climate change.

Abstract ：
Tomato fruit size is a crucial trait in domestication, determined by cell division and cell expansion. Despite the identification of several quantitative trait loci associated with fruit size in tomatoes, the underlying molecular mechanisms that govern cell division and expansion to control fruit size remain unclear. CRISPR/Cas9 gene editing was used to generate single and double loss-of-function mutants of the tomato STERILE APETALA1 (c) and SlSAP2. The results demonstrate that the two SlSAP genes function redundantly in regulating leaf and fruit size by positively regulating cell proliferation and expansion, with SlSAP1 having the predominant effect. Consistently, overexpression of either SlSAP1 or SlSAP2 leads to enlarged fruits due to an increase in both cell layers and cell size in the pericarp. Biochemical evidence suggests that both SlSAP1 and SlSAP2 can form an SCF complex and physically interact with SlKIX8 and SlKIX9, which are crucial negative regulators of fruit size. Further results reveal that SlSAP1 and SlSAP2 target them for degradation. This study uncovers that the ubiquitination pathway plays an important role in the determination of tomato fruit size, and offers new genetic loci for improving fruit yield and biomass by manipulating pericarp thickness.

Abstract ：
Plant trichomes serve as essential physical barriers and highly specialized metabolic powerhouses, producing a vast array of ecologically and economically significant compounds. While the MYB-bHLH-WD40 (MBW) complex governing unicellular trichome development in Arabidopsis thaliana is well-established, accumulating evidence suggests the existence of distinct mechanisms in regulating multicellular trichomes in other plant species. This review summarizes recent breakthroughs revealing significant divergence in species forming multicellular and glandular trichomes. The molecular networks orchestrating trichome fate determination and morphogenesis are focused, emphasizing the pivotal role and dose-dependent mechanisms of homeodomain-leucine zipper class IV (HD-Zip IV) transcription factors. This review highlights the complexity and species specificity of trichome developmental programming. Understanding these underlying developmental blueprints is fundamental for elucidating how plants build these metabolic powerhouses and holds promise for future applications in enhancing plant defense and optimizing natural product biosynthesis.
