Plant Science Research Weekly: June 7th
WWR Full PostReview: Source–sink regulation in crops under water deficit ($)
Plants have a remarkable ability to coordinate cellular activities across huge distances, yet we have only a basic understanding of how these remote activities are coordinated. A review by Rodrigues et al. summarizes what we know about…
Designer pentatricopeptide repeat PPR protein as RNA affinity tag (Plant Cell)
Plant Science Research WeeklyPentatricopeptide repeat (PPR) proteins bind RNA, using a code in which specific amino acid motifs recognize specific bases, similar to TAL effector proteins. In plants, PPR proteins localize almost exclusively to mitochondria and chloroplasts, with functions including RNA, stabilization, splicing and…
Review: Source–sink regulation in crops under water deficit ($) (Trends Plant Sci)
Plant Science Research WeeklyPlants have a remarkable ability to coordinate cellular activities across huge distances, yet we have only a basic understanding of how these remote activities are coordinated. A review by Rodrigues et al. summarizes what we know about the relationship between source (e.g., photosynthetic tissues) and…
Gene networks underlying cannabinoid and terpenoid accumulation in cannabis (Plant Physiol)
Plant Science Research WeeklyRecent changes in the legal status of cannabis and cannabis-products have allowed renewed scientific interest in the genetic and metabolic basis of cannabis’ effects as well as the regulatory issues related to quality control of the products. Many varieties of Cannabis spp. have poorly documented pedigrees,…
Embryo protection after germination in date palm (Plant Cell)
Plant Science Research WeeklyPlant morphogenesis is a dynamic process that can be modulated in response to environmental cues. In this work, Xiao et al. characterized germination and seedling development in date palm. After germination, the cotyledonary petiole grows, but the embryo development is paused. At early stages of development…
Auxin-mediated statolith production for root gravitropism (New Phytol)
Plant Science Research WeeklyPlants have evolved the ability to perceive and respond to gravity, one of the most persistent external cues. This response process, termed gravitropism, has been extensively studied for its importance in plant development and its potential to improve agronomic traits of crops. The gravitropic response…
Genetic and Molecular analysis of trichome development in Arabis alpina $ (PNAS)
Plant Science Research WeeklyTrichomes (plant hairs), arise from epidermal cells of plants. The molecular mechanism involved in the development of trichomes of plants has been well studied in Arabidopsis thaliana. In this paper, Chopra et al. have identified key regulators of leaf trichome development in Arabis alpina, a species…
