Drought conditions reduce root-feeding nematode predator populations (PNAS)
Plant Science Research WeeklyClimate change is expected to cause numerous negative impacts on plant populations. An under considered area that will be affected are the communities of soil organisms that rely on a delicate balance of environmental conditions, particularly in grasslands that receive moderate precipitation (mesic grasslands).…
ABCB21 regulates auxin levels in cotyledons, pericycle and leaves (Frontiers Plant Science)
Plant Science Research WeeklyAuxin activity is maintained through regulated biosynthesis, metabolism and transport. In this paper Jenness et al. characterized the physiological significance of a known IAA transporter, ABCB21 (ATP BINDING CASSETTE TRANSPORTER subfamily B member 21) in Arabidopsis. ABCB21 transports shoot derived…
Pipecolic contributes to systemic acquired resistance in barley ($) (MPMI)
Plant Science Research WeeklySystemic acquired resistance (SAR) is a robust long-distance immune response mediated by a diverse contingent of candidate phloem-mobile signals that prime distal uninfected tissues for enhanced resistance to future infections. The lysine-derived catabolite pipecolic acid (Pip) has emerged as a key mediator…

WWR Full PostReview: A series of fortunate events: Introducing Chlamydomonas as a reference organism
Clamydomonas reinhardtii is the most thoroughly characterized unicellular alga. Like yeast, it is a single-celled eukaryotic organism that is easy to culture, and it lives predominantly in its haploid form but…

Setting Time for a Hot Date: Paused Embryo Development and Protective Organogenesis Allow Dates to Cope with the Desert Environment
Research, The Plant Cell, The Plant Cell: In BriefAdaptive developmental plasticity, in which changing environmental conditions modulate morphogenesis, can help organisms survive harsh conditions. Common examples include the protection of shoot apical meristems by transient arrest and sequestration into bud-like structures in wintering evergreens (e.g.…

Epigenetic regulation of mRNA polyadenylation site selection
Plant Physiology, Plant Physiology: News and Views, ResearchThe transcription of many genes is regulated through alternative splicing, with over 60 percent of genes in Arabidopsis thaliana producing more than one mRNA [1]. The most common forms of alternative splicing are intron retention and the use of alternative polyadenylation sites that result in transcripts…
