identification and expression analysis of pin-like (pils) gene family of rice treated with auxin and cytokinin.	the phytohormone auxin is one of the most important signaling molecules that undergo accumulation or depletion in a temporal or spatial manner due to wide arrays of changes in developmental or stress programs. proper distribution, maintenance and homeostasis of auxin molecules across the plant systems are one of the most important phenomena required for proper growth and development of plant. the distribution and homeostasis of auxin is maintained by auxin transport systems across the plant. the ...	2015	26193322
brassinosteroid signaling regulates leaf erectness in oryza sativa via the control of a specific u-type cyclin and cell proliferation.	leaf erectness is key in determining plant architecture and yield, particularly in cereal crops. brassinosteroids (brs) play a unique role in controlling this trait in monocots, but the underlying cellular and molecular mechanisms remain big mysteries. here we report that the abaxial sclerenchyma cell number of rice lamina joints (ljs) is closely related to leaf erectness, and br signaling tightly regulates their proliferation. we identified a rice u-type cyclin cyc u4;1 enriched in rice ljs, wi ...	2015	26190148
ethylene biosynthesis is promoted by very-long-chain fatty acids during lysigenous aerenchyma formation in rice roots.	in rice (oryza sativa) roots, lysigenous aerenchyma, which is created by programmed cell death and lysis of cortical cells, is constitutively formed under aerobic conditions, and its formation is further induced under oxygen-deficient conditions. ethylene is involved in the induction of aerenchyma formation. reduced culm number1 (rcn1) is a rice mutant in which the gene encoding the atp-binding cassette transporter rcn1/osabcg5 is defective. here, we report that the induction of aerenchyma forma ...	2015	26036614
